Description
Technical field
The invention belongs to geotechnical slope protection technology field, more particularly to the ecological TGXG of a kind of side slope protection and its
Construction method.
Background technology
With the development of China's infrastructure construction, a large amount of highway is started building with railway, the excavation of cubic metre of earth and stone side slope
Original vegetative coverage is destroyed, the exposed of a large amount of soil properties and rock slope is caused, leads to serious soil erosion, generates falling rocks
Etc. security risks while destruction is also resulted in ecological environment.The high precipitous rock slope that especially engineering construction carries over,
Lack the edaphic condition, nutrient condition and moisture condition of plant growth, to which plant survival rate can be caused low, can be used in integrating
The technology of protection and greening is seldom.Conventional concrete safeguard structure easily causes visual aestheticly tired.
Before making the present invention, found out serial of methods in terms of alien earth sparging both at home and abroad, but still there are many
It needs to continuously improve and improve place.Such as side slope is sowed grass seeds by duster to add seed, paper pulp fiber, fertilizer and binder to be sprayed onto after water and be needed
In the side slope to be afforested, a large amount of seed wastes are caused, and a large amount of water soluble fertilizers outflow with water, cost is higher.
In recent years, TGXG is applied more and more extensive in slope protection project.It is commonly used for the muscle material of earth structure
Or the muscle material etc. of composite material.Compared with other geosynthetics, it have effects that unique performance and, for ensure ground work
The safety of journey structure plays an important role.But the past generally only considered its protection effect using TGXG bank protection,
Its green, ecology and environmental protection effect are not accounted for.
Invention content
It is an object of the invention to not account for the deficiency of its ecological effect for existing TGXG, propose that one kind is used for
The ecological TGXG and its construction method of side slope protection solve plant life bad environments in existing side slope protection, greening effect
The undesirable problem of fruit reinforcing side slope and can accomplish to afforest for a long time, realize the engineering reinforcement of side slope and the dual effect of greening
Fruit.
To realize the present invention purpose and the technical solution adopted is that such, a kind of geotechnological lattice of ecology for side slope protection
Grid, it is characterised in that:
Include mainly TGXG protection network, anchor structure, Nutrition Soil, vegetable seeds, several water-supply-pipes.
TGXG protection network is made of crisscross tubulose TGXG, and side slope is laid on by anchor structure fixation
Surface.
Inner containment Nutrition Soil, vegetable seeds and the water-supply-pipe of the tubulose TGXG.
The water-supply-pipe is located at the intracavity bottom of tubulose TGXG, and is fixed with the inner wall of tubulose TGXG.It is described
The tube wall of water-supply-pipe upward has several osculums.
The upper surface of the TGXG protection network has several plant growth holes.These plant growth holes are to be opened in pipe
Through-hole on the tube wall of shape TGXG upward.Plant growth hole is blocked using band mesh knitted cloth.
Further, it is distributed fine hole in tubulose TGXG.
Further, the water-supply-pipe in the tubulose TGXG is crisscross, forms water-supply-pipe network system.
Further, the water-supply-pipe is hose.
Further, the anchor structure includes several soil nailings.TGXG protection network is fixed on side slope by these soil nailings
On.
Invention additionally discloses the construction methods for above-mentioned ecological TGXG, which is characterized in that is walked including following technology
Suddenly：
1) in the good tubulose TGXG of plant produced, the i.e. earth work grille net of tubulose.There is preformed hole among earth work grille net
Hole forms crisscross hollow pipeline network, has water-supply-pipe to be fixed together with earth work grille net in hole, water-supply-pipe
Form crisscross aqueduct network system.
2) Nutrition Soil is prepared, includes fertilizer needed for vegetable seeds and plant growth in Nutrition Soil.
3) Nutrition Soil is circulated into the hole inside earth work grille net.
Ecological earth work grille net with water-supply-pipe and Nutrition Soil 4) is transported to the top of the slope position of side slope.
5) earth work grille net is spread out in the slope surface of side slope from top to bottom, is allowed to cover entire side slope.
6) by soil nailing that earth work grille net is fixed in side slope.
7) water-supply-pipe water flowing makes Nutrition Soil moisten, ensure plant seed germination and growth needed for moisture, water-flowing amount according to
Local rainfall flexible modulation.
8) vegetable seeds passes through the micro- of TGXG net surface in the moist lower germinating growth of rainwater and soil body nutritional ingredient
Pore hole is longer, makes slope greening.
Advantages of the present invention and effect are：Active protecting net is become by traditional protection network as by TGXG and anchoring
The side slope protection and hardened system that system collectively constitutes, ensure that the stability of side slope；The Nutrition Soil placed in TGXG can
Climbing plant is planted, realizes the covering of the greening and anti-rain drop erosion vegetation to geotechnical slope；Nutrition Soil is placed on TGXG
Inside is used in combination woven cloth with holes to cover, ensure that its stability；It is plant to supply water with water-supply-pipe and combine local rainwater supply
Growth provide long-term and enough nutrient solution and moisture, while plant being enable preferably to resist the variation of external environment；This
It is anti-can to solve existing geotechnical slope for the protecting slope ecology system that invention is made of TGXG protection network, anchor pole and vegetation
Plant life bad environments in shield, the undesirable problem of afforestation effect not only strengthen side slope, but also can accomplish to afforest for a long time, realize
The ecology that slope project is reinforced.
